Method and apparatus for ultrasonic machining

1. A method for machining a component, said method comprising:

aligning a component in a machining apparatus configured to induce vibrations such that a vibration direction of the machining apparatus is substantially aligned with respect to a machining direction of the component wherein the machining apparatus has a body having a first projection and a second projection extending therefrom, wherein the first projection comprises a first mating surface, the second projection comprises a second mating surface, and the first and second projections are spaced apart by a gap, at least a portion of the component being received in the gap, wherein the machining apparatus includes a machining tool including a cross-bar and a plurality of cutters coupled thereto; and

vibrating the body in the vibration direction to machine a portion of the component in the machining direction wherein the portion of the component received in the gap is not machined.

2. A method in accordance with claim 1 further comprising aligning the machining direction of the component substantially parallel with the vibration direction of the machining apparatus.

3. A method in accordance with claim 1 wherein vibrating the machining apparatus comprises vibrating the machining apparatus such that at least one opening is machined to extend into the component in the machining direction.

4. A method in accordance with claim 1 wherein providing the machining apparatus with a machining tool further comprises:

providing the machining apparatus with a machining tool that includes a third mating surface and a fourth mating surface; and

coupling the cross-bar to the body between the first and second projections using an adhesive to facilitate efficient transmission of vibrational energy between the body and the cross-bar.

5. A method in accordance with claim 4 wherein providing a machining apparatus comprises:

serrating the first, second, third, and fourth mating surfaces to facilitate efficient transmission of vibrational energy between the body and the cross-bar; and

coupling the cross-bar to the body between the first and second projections by coupling the first mating surface to the third mating surface and the second mating surface to the fourth mating surface.

6. A method in accordance with claim 1 wherein vibrating the body comprises ultrasonically vibrating the body.

7. A method for machining a component said method comprising:

providing a machining apparatus configured to induce ultrasonic vibrations, the machining apparatus including a body, and a first projection and a second projection that extend from the body and that are spaced apart such that a gap is defined therebetween, and wherein a cross-bar is spaced from the body and extends between the first and second projections;

aligning a component to be machined with the machining apparatus such that a portion of the component is received in the gap defined by the first and second projections of the body, the portion of the component being positioned between the body and cross-bar;

contacting the component with the machining tool; and

ultrasonically vibrating the machining tool to machine the component, wherein a plurality of cutters are coupled to the cross-bar.

8. A method in accordance with claim 7 further comprising:

removing the cross-bar from the body before aligning the component the machining apparatus; and

re-assembling the cross-bar after the component has been aligned.
